History[ edit ] A sketch of the Pearl Street Station Intwo electricians built the world's first power system at Godalming in England. It was powered by two waterwheels and produced an alternating current that in turn supplied seven Siemens arc lamps at volts and 34 incandescent lamps at 40 volts.

The Pearl Street Electrical systems cars initially powered around 3, lamps for 59 customers. Direct current power could not be transformed easily or efficiently to the higher voltages necessary to minimise power loss during long-distance transmission, so the maximum economic distance between the generators and load was limited to around half a mile m.

Perhaps the most serious was connecting the primaries of the transformers in series so that active lamps would affect the brightness of other lamps further down the line. Budapest perfected the secondary generator of Gaulard and Gibbs, providing it with a closed iron core, and thus obtained the first true power transformer, which he dubbed with its present name.

Kennedy inin which several power transformers have their primary windings fed in parallel from a high-voltage distribution line. The system was presented at the National General Exhibition of Budapest.

In George Westinghousean American entrepreneur, obtained the patent rights to the Gaulard-Gibbs transformer and imported a number of them along with a Siemens generator, and set his engineers to experimenting with them in hopes of improving them for use in a commercial power system.

Inone of Westinghouse's engineers, William Stanleyalso recognised the problem with connecting transformers in series as opposed to parallel and also realised that making the iron core of a transformer a fully enclosed loop would improve the voltage regulation of the secondary winding.

These networks were effectively dedicated to providing electric lighting. During this time the rivalry between Thomas Edison and George Westinghouse's companies had grown into a propaganda campaign over which form of transmission direct or alternating current was superior, a series of events known as the " War of Currents ".

Inafter a protracted decision-making process, alternating current was chosen as the transmission standard with Westinghouse building the Adams No. In the first experimental high voltage direct current HVDC line using mercury arc valves was built between Schenectady and Mechanicville, New York.

It consisted of a layer of selenium applied on an aluminum plate. Ina General Electric research group developed a solid-state p-n-p-n switch device that was successfully marketed in earlystarting a revolution in power electronics. Inalso Siemens demonstrated a solid-state rectifier, but it was not until the early s that solid-state devices became the standard in HVDC, when GE emerged as one of the top suppliers of thyristor-based HVDC.

For example, the development of computers meant load flow studies could be run more efficiently allowing for much better planning of power systems. Advances in information technology and telecommunication also allowed for remote control of a power system's switchgear and generators.

Basics of electric power[ edit ] An external AC to DC power adapter used for household appliances Electric power is the product of two quantities: These two quantities can vary with respect to time AC power or can be kept at constant levels DC power.

electrical books,electrical exam books,videos,audio tapes and seminars to help you prepare for the electrical exam. The alternator is your car’s electrical charger. It’s various parts are contained in an aluminum housing and generate direct current for recharging your vehicle’s battery. Your vehicle’s alternator also helps power the other electrical loads of your car. The battery is the backbone of your vehicle’s electrical system . Spot car electrical system warning signs early and avoid getting stuck. Signs include an engine that will not crank or cranks slowly, cars that need jump start, dashboard warning lights stay on after the engine is running and more.

Most refrigerators, air conditioners, pumps and industrial machinery use AC power whereas most computers and digital equipment use DC power the digital devices you plug into the mains typically have an internal or external power adapter to convert from AC to DC power.How Electrical Systems Work A car's electrical system is not that complicated Every car's electrical system is composed of a wiring harness that connects various computer, controllers, lights, actuators, motors and switches.

Prospective students who searched for Online Electrical Car Systems Course Information found the following information and resources relevant and helpful.

Testing Electrical Systems with a Digital Multimeter Perhaps the most important tool you'll use in troubleshooting auto electrical systems is the multimeter. Electrical polarity is a term used throughout industries and fields that involve electricity.

There are two types of poles: positive (+) and negative (−).

This represents the electrical potential at the ends of a circuit. A battery has a positive terminal (+ pole) and a negative terminal (− pole). Many cars will soon have volt electrical systems.

They’ll power stop-start motors, hybrid motors, and turbochargers, allowing for smaller engines with better fuel economy and performance.
